Figure 2

Effect of different treatments of copper (Cu) and chromium (Cr) on the contents of glutathione metabolism in leaves and roots of two Brassica napus cultivars. (a, b) Glutathione reductase (GR); (c, d) reduced glutathione (GSH); (e, f) oxidized glutathione (GSSG); (g, h) reduced glutathione/oxidized glutathione (GSH/GSSG) ratio. Each value in the graphs represents the mean with standard deviation of three replications. Means followed by different letters indicate significant difference at , according to Duncan’s test.
